Abstract: 1329132 Bonded fibre fabrics CARL FREUDENBERG 28 Oct 1970 [6 Nov 1969] 51272/70 Heading D1R [Also in Division B2] A discontinuous coating of a heat sensitive adhesive is applied to a corded cross-lapped non-woven fabric of 55-98% first fibres and 2-45% second lower melting, fibres which is consolidated by hot calendering at 100-200‹C to soften the second fibres, then impregnated with a dispersion or solution of a second binder. The first fibres may comprise cotton, nylon 6, nylon 66, polyester or other fibres with a melting point above 230‹C, or a mixture of the above fibres. The second fibres may be nyion 6, 11 or 12, copolyamides such as nylon 6/66, 6/11, 6/12, 66/11 or 66/12, ethylylene terephthalate/isophthalate copolymer, or ethylene/vinyl alcohol copolymer, a plasticiser being added if necessary to lower the melting point. Calendering, using a metal calender and a rubber belt, or a suction drum, may be carried out at a temperature and pressure such that the second fibres soften, or such that they lose their fibre structure. The consolidated fleece has a density of 0.12 to 0.16. It is impregnated with an aqueous dispersion of butadiene/ chloroprene, butadiene/acrylonitrile/methlyolocrylamide or butadiene/styrene/methacrylic acid plus a trimethylolated melamine resin for crosslinking, or with a dispersion of acrylic ester or polyurethane, or with a dimethylformamide solution of polyurethane formed from glycol adipate, 1,4-butadiene and diphenylmethane diisocyanate. The binder may be coagulated, by heat, water or other solvent acrylonitrile/methylolocrylamide or butadiene/ styrene/methacrylic acid, plus a trimethylolated melamine resin for cross-linking, or with a dispersion of acrylic ester or polyurethane, or with a dimethylformamide solution of polyurethane formed from glycol adipate, 1,4-butadiene and diphenylmethane diisocyanate. The binder may be coagulated, by heat, water or other solvent. A discontinuous coating of polyethylene, polyamide, polyacrylate or polyvinyl chloride plasticised with benzyl butyl phthalate or other heat sensitive adhesive is applied by printing, spraying or the scattering of powder. The fleece is used as an interlining, being laminated to the outer layer of a garment by hot-pressing. The binders are dry cleaning resistant.

Title: Method of and apparatus for spinning metallic filaments
Inventor: KAVESH S
IPC: D01F9/08
Filed: 1973-11-09
Abstract: 1458017 Continuous casting ALLIED CHEMICAL CORP 9 Nov 1973 [14 Nov 1972] 52221/73 Heading B3F [Also in Division C7] Metal is melted (e.g. in an inert atmosphere in a quartz, zirconia or beryllia crucible 21 with heating coil 31 and at least one, preferably tapered, orifice 23 for extrusion) and a jet of the melt is passed through a zone 41 of He, or of a gas such as air for promoting the formation of a stabilizing film on the jet, into a liquid flowing as a coherent stream in the same direction as the jet from which liquid it is recovered as a solid filament. The liquid may react with the jet to form a stabilizing film on it (sulphide ion in a solution for quenching a jet mainly of Cu is said to provide a sulphide film). The pressure of inert gas (supplied from a source 45a) in a chamber 24 containing the crucible 21 extrudes the melt. A pyrometer 29 is used to measure the temperature. By the quenching, an amorphous structure or an equiaxed or oriented crystalline structure may be produced. As shown, quenching liquid is forced down through holes in a ring 30 into a standpipe 33 to establish the flow in the direction of the filament travel. The filament is caught in a basin 35 from which the liquid is pumped through a refrigeration unit 37 back into a main reservoir 47. The liquid may be water or may be a solution of NaCl at less than 0 C., of MgCl 2  at less than - 20 C. or of ZnCl 2  at less than - 30 C. An emulsion or solid-liquid dispersion may also be used. The ring 30 inhibits the formation of a vortex above and in the standpipe 33 but this may be done by baffles (Figs. 2, 4, not shown). By permitting a vortex to form, a serrated filament may result if required, or if the jet velocity exceeds that of the liquid, a corkscrew-like shape can be obtained if there is a vortex. Without the latter a corrugated filament is obtained. With a slow liquid speed and a vortex, kinked filaments result. With superheated metal there is a series of beads along the filament. In another apparatus (Fig. 5, not shown), the melt jet is discharged on to an inclined shoot, down which the quenching liquid flows. The filament may be of Al, Ag, Au, Be, Bi, Ca, Cd, Ce, Co, Cr, Cu, Er, grey Fe, Hf, Ho, La, Mg, Mn, Nd, Ni, Os, Pd, Pb, Pr, Re, Ru, Sc, Sn, Tl, Ti, Y, Zn or of a Ni-Fe or Pb-Sn alloy. Diameters in the range 0À005-0À06 inches are quoted.
